Description
Technical Field
[0001] The invention relates to the technical field of chlorine removal devices, and in particular to a photocatalytic total chlorine removal device for dialysis water. Background Art
[0002] Dialysis is a method of treating renal failure by simulating the filtration function of the kidneys to remove excess metabolic waste and water from the body in order to maintain a stable internal environment. Dialysis therapy is divided into two forms: hemodialysis and peritoneal dialysis. During treatments such as hemodialysis or peritoneal dialysis, dialysis water is needed, which can be used to clean the dialyzer and dialysis tubing and keep the equipment and tubing clean. At the same time, dialysis water is an important substance for maintaining water and electrolyte balance in dialysis patients. The solute components in it need to be added to the dialysis water in a certain proportion. Therefore, dialysis water is also needed to prepare dialysis fluid, and dialysis patients also need to use dialysis water when changing dressings, cleaning wounds, etc.
[0003] At present, most of the domestic hemodialysis water equipment uses an activated carbon filter as a residual chlorine removal device. However, after a certain period of adsorption, the activated carbon will gradually reach the adsorption saturation state, and it needs to be regenerated to restore its adsorption capacity. However, the performance of the regenerated activated carbon may be affected, reducing its adsorption effect, and after the filter reaches the saturation state, even if chlorine enters, it will be fixed on the filter element, causing it to fail. At the same time, for high-concentration chlorine, its removal effect is not obvious. Excessive residual chlorine in dialysis water will cause hemolysis in dialysis patients, which is a serious threat to hemodialysis safety.
[0004] The preferred method in the prior art is to remove chlorine through some specific light waves, such as ultraviolet rays and other specific light waves with a wavelength of 200-253nm, to oxidize the chlorine in the water into harmless chlorides, thereby achieving the purpose of purifying the water quality. Since the photocatalytic activity is affected by factors such as light intensity and catalyst materials, the photocatalytic activity of the photocatalytic device may be insufficient, which makes it difficult to effectively remove chlorine in the water, resulting in a small amount of chlorine remaining in the equipment, posing a potential threat to human health and the environment.

The uniform part is installed in the two first cylinders 2 for uniform photocatalytic reaction. The driving part is installed on the fixed frame 1 to drive the uniform part to rotate around the corresponding water treatment cylinder 3.
[0084] Specifically, when using ultraviolet light waves of a specific wavelength to dechlorinate the water body, first open the water inlet 4, pass water into the water inlet 4, so that the water first enters the water treatment cylinder 3 in the upper first cylinder 2, turn on the two ultraviolet lamps 6, and perform photocatalytic dechlorination on the water in the water treatment cylinder. Under the action of the soft light cover 7, the refraction of light can be increased without affecting the ultraviolet effect. After the water passes through the first water treatment cylinder 3, it will flow into the second water treatment cylinder 3 through the connecting pipe 5 for further treatment. During the treatment process, the drive part is started to drive the uniform part to work, thereby uniformizing the catalytic reaction of light and improving the dechlorination effect of the water. Then, the treated water will enter the residual chlorine treatment component under the action of the drainage component, and the dechlorinated water will be further treated, thereby further reducing the chlorine in the water, reducing the safety of hemodialysis caused by incomplete chlorine treatment in the water due to a small amount of chlorine remaining in the equipment, and the water after further filtration will enter the residual chlorine detection component, and the residual chlorine detection component is started to detect the water discharged from the drainage component, and qualified dialysis water will be discharged.
[0085] As mentioned above, the uniformity part includes a rotating ring 8, a gear ring 9, a spiral soft light belt 10 and an ultraviolet light belt 11. The rotating rings 8 are rotatably installed at both ends of the two first cylinders 2. The four rotating rings 8 are rotatably matched with the corresponding water treatment cylinders 3. The gear rings 9 are fixedly installed on the four rotating rings 8. The spiral soft light belts 10 are fixedly installed between the rotating rings 8 at both ends of the two first cylinders 2, and the ultraviolet light belts 11 are fixedly installed on the two spiral soft light belts 10.
[0086] Specifically, when the uniform light catalyzes the reaction of water to improve the dechlorination effect, the driving part is started to drive the four gear rings 9 to rotate simultaneously, the four gear rings 9 respectively drive the corresponding rotating rings 8 to rotate in the first cylinder 2, and the four rotating rings 8 respectively drive the corresponding spiral soft light belts 10 to rotate. At this time, the ultraviolet light belt 11 is started, and under the action of the spiral soft light belt 10, the refraction of ultraviolet rays is increased, thereby improving the dechlorination effect of water.
[0087] As mentioned above, the driving part includes a connecting frame 12, a transmission shaft 13, a first gear 14 and a first motor 15. Two connecting frames 12 are symmetrically installed between the two first cylinders 2. The transmission shaft 13 is rotatably installed between the two connecting frames 12.

[0089] The residual chlorine treatment component is installed inside the fixed frame 1, and is used to further treat the residual chlorine in the water after being treated by the photocatalytic component. The residual chlorine treatment component includes a supporting frame 16, an outer shell 17, a mobile frame 18, a filtering part and a sliding part. The supporting frame 16 is fixedly installed on the inner bottom wall of the fixed frame 1, the outer shell 17 is fixedly installed at the water outlet end of the supporting frame 16, and the mobile frame 18 is slidably installed inside the supporting frame 16. Two filtering parts are installed inside the mobile frame 18 for filtering the residual chlorine in the water. The sliding part is installed at the bottom of the fixed frame 1 to drive the mobile frame 18 to move.
[0090] Specifically, after photocatalytic dechlorination, there may still be some residual chlorine in the water. If the chlorine is not effectively removed, it will affect the water quality. At this time, the sliding part is started first to adjust the position of the movable frame 18 in the supporting frame 16, so as to adjust the position of the filter part. When the water after photocatalytic dechlorination enters the filter part, it will undergo secondary filtration, and then the water after secondary filtration will enter the outer shell 17. At this time, the water entering the outer shell 17 is tested, and when the water meets the use requirements of dialysis water, it can be discharged.
[0091] As mentioned above, the filter part includes a filter cartridge 19, a sealing cover 20, a connecting ring 21 and an activated carbon filter element 22. Two filter cartridges 19 are symmetrically and fixedly installed on the mobile frame 18. The sealing covers 20 are removably and sealably installed on the two filter cartridges 19. The connecting ring 21 is fixedly installed on the two sealing covers 20 and the water inlet end of the supporting frame 16, and the activated carbon filter element 22 is fixedly installed in the other two sealing covers 20.
[0092] Specifically, after the water after photocatalytic dechlorination enters the filter cartridge 19, the water entering the filter cartridge 19 will be filtered by the activated carbon filter element 22 and then flow out. Then, the water after secondary filtration will be discharged into the outer shell 17 through the connecting ring 21 on the sealing cover 20. The sealing cover 20 and the filter cartridge 19 are preferably detachably connected by a threaded connection.
[0093] The above-mentioned also includes a sealing ring 23, a first electric cylinder 24, a sliding ring 25 and a casing 26 of the sealing assembly. The ends of the two filter cartridges 19 close to the water inlet end of the supporting frame 16 and the end of the casing 17 close to the filter cartridge 19 are connected with the sealing ring 23. Multiple first electric cylinders 24 are fixedly installed at equal angles on the three sealing rings 23. Sliding rings 25 are sealed and slidably installed inside the three sealing rings 23. The sliding rings 25 are fixedly connected to the output ends of the corresponding multiple first electric cylinders 24. The three sliding rings 25 are adapted to the corresponding connecting rings 21. The fixed frame 1 is located on both sides of the casing 17 and the casing 26 can be removably installed. The position of the casing 26 corresponds to the filter cartridge 19.
[0094] Specifically, after the mobile frame 18 drives the corresponding filter cartridge 19 to move to the working position, the first electric cylinder 24 on the sealing ring 23 on the corresponding filter cartridge 19 and the first electric cylinder 24 on the sealing ring 23 on the outer shell 17 are started, and the first electric cylinder 24 drives the corresponding sliding ring 25 to move until the sliding ring 25 on the outer shell 17 is connected with the connecting ring 21 on the filter cartridge 19, and the sliding ring 25 on the filter cartridge 19 is connected with the connecting ring 21 at the water inlet end of the support frame 16. At this time, the water after photocatalytic dechlorination can be discharged into the filter cartridge 19. When the activated carbon filter element 22 in the filter cartridge 19 at the working position is saturated, the first electric cylinder 24 can be retracted at this time, and then the filter cartridge 19 is driven to move by the mobile frame 18 until another filter cartridge 19 moves to the working position, and then the casing 26 at the corresponding position is removed, the saturated activated carbon filter element 22 is removed, and a new activated carbon filter element 22 is replaced, and then the casing 26 is installed back.
[0095] As mentioned above, the sliding part includes a sliding frame 27, a screw 28, a second motor 29 and a threaded block 30. The sliding frame 27 is fixedly installed at the bottom of the fixed frame 1. The screw 28 is rotatably installed in the sliding frame 27. The second motor 29 is fixedly installed inside the fixed frame 1. The second motor 29 is fixedly connected to the screw 28. A threaded block 30 is threadedly sleeved on the screw 28. The threaded block 30 is fixedly connected to the movable frame 18.
[0096] Specifically, when the movable frame 18 is driven to move, the second motor 29 is started, and the second motor 29 drives the screw rod 28 to rotate in the sliding frame 27, and the screw rod 28 drives the threaded block 30 to move, that is, the movable frame 18 is driven to move by the threaded block 30.
[0097] The residual chlorine detection component is installed on the residual chlorine treatment component, and is used to detect the residual chlorine after treatment. The residual chlorine detection component includes a detector 31, a detection head 32 and a water outlet 33. The detector 31 is fixedly installed on the outer shell 17. The detection head 32 is fixedly installed at the bottom of the detector 31.

[0098] Specifically, after the water enters the housing 17 after the secondary detection, the detector 31 is started. The detector 31 detects the water after entering the housing 17 through the detection head 32. If the water is qualified, the water outlet 33 can be opened to discharge the water.
[0099] The drainage component is installed on the inner bottom wall of the fixed frame 1, and is used to discharge water treated by the photocatalytic component into the residual chlorine treatment component. The drainage component includes a water pump 34, a water inlet pipe 35, a drain pipe 36 and a valve 37. The water pump 34 is fixedly installed inside the fixed frame 1. The input end of the water pump 34 and the end of the water treatment cylinder 3 located at the bottom away from the connecting pipe 5 are connected by the water inlet pipe 35. The output end of the water pump 34 is connected to the connecting ring 21 on the water inlet end of the mobile frame 18, and a valve 37 is fixedly installed on the drain pipe 36.
[0100] Specifically, start the water pump 34, which extracts the water after photocatalytic dechlorination through the water inlet pipe 35 and then sends it to the drain pipe 36. After the filter cartridge 19 moves to the working position, open the valve 37 to discharge the water into the corresponding filter cartridge 19 through the drain pipe 36.
[0101] To summarize, when using ultraviolet light waves of a specific wavelength to dechlorinate water, first open the water inlet 4, pass water into the water inlet 4, so that the water first enters the water treatment cylinder 3 in the upper first cylinder 2, turn on the two ultraviolet lamps 6, and perform photocatalytic dechlorination on the water in the water treatment cylinder. Under the action of the soft light cover 7, the refraction of light can be increased without affecting the ultraviolet effect. After the water passes through the first water treatment cylinder 3, it will flow into the second water treatment cylinder 3 through the connecting pipe 5 for further treatment.
[0102] During the treatment process, the first motor 15 is started, and the first motor 15 drives the transmission shaft 13 to rotate. The transmission shaft 13 drives the two first gears 14 to rotate at the same time. The two first gears 14 respectively drive the corresponding gear rings 9 to rotate, thereby driving the four gear rings 9 to rotate at the same time. The four gear rings 9 respectively drive the corresponding rotating rings 8 to rotate in the first cylinder 2. The four rotating rings 8 respectively drive the corresponding spiral soft light belts 10 to rotate. At this time, the ultraviolet light belt 11 is started. Under the action of the spiral soft light belt 10, the refraction of ultraviolet rays is increased, thereby improving the dechlorination effect of water, uniforming the light catalytic reaction, and improving the dechlorination effect of water.
[0103] After photocatalytic dechlorination, there may still be some residual chlorine in the water. If the chlorine is not effectively removed, it will affect the water quality. At this time, the second motor 29 is started first, and the second motor 29 drives the screw 28 to rotate in the sliding frame 27, and the screw 28 drives the threaded block 30 to move, and the threaded block 30 drives the movable frame 18 to move, so as to adjust the position of the movable frame 18 in the supporting frame 16, and then adjust the position of the filter cartridge 19, and then start the water pump 34, and the water pump 34 is driven by the inlet. The water pipe 35 extracts the water after photocatalytic dechlorination and then sends it to the drain pipe 36. After the filter cartridge 19 moves to the working position, the first electric cylinder 24 on the sealing ring 23 on the corresponding filter cartridge 19 and the first electric cylinder 24 on the sealing ring 23 on the housing 17 are started. The first electric cylinder 24 drives the corresponding sliding ring 25 to move until the sliding ring 25 on the housing 17 is connected to the connecting ring 21 on the filter cartridge 19, and the sliding ring 25 on the filter cartridge 19 is connected to the connecting ring 21 at the water inlet end of the support frame 16.
[0104] At this time, the valve 37 can be opened to discharge the water after photocatalytic dechlorination into the corresponding filter cartridge 19 through the drain pipe 36. The water entering the filter cartridge 19 will be filtered by the activated carbon filter element 22 and then flow out. Then, the water after secondary filtration will be discharged into the housing 17 through the connecting ring 21 on the sealing cover 20 for secondary filtration, thereby further reducing the chlorine in the water and reducing the safety of hemodialysis caused by incomplete chlorine treatment in the water due to a small amount of chlorine remaining inside the equipment. After the water after the secondary detection enters the housing 17, the detector 31 is started. The detector 31 detects the water after entering the housing 17 through the detection head 32. If the water meets the use requirements of dialysis water, the water outlet 33 can be opened to discharge the qualified dialysis water.
[0105] When the activated carbon filter element 22 in the filter cartridge 19 at the working position is saturated, the detector 31 will sound an alarm, then close the valve 37, retract the first electric cylinder 24, and then move the filter cartridge 19 by moving the frame 18 until the other filter cartridge 19 moves to the working position.
